While it's true that enantiornithines have proved to be a diverse, speciose clade, the problem with such groups is that people soon come to assume that any and all new species are members of said groups.

And Yanornis isn't an enantiornithine - it's a member of a small clade of Cretaceous birds that are more closely related to neornithines than enantiornithines are

This is reminiscent of what's seen in various enantiornithines and other Mesozoic birds, though the posterolateral processes aren't normally as divergent as they are in

Named for a near-complete specimen, Aberratiodontus was regarded by its describers (Gong et al. 2004) as one of the most unusual of the enantiornithines or 'opposite birds' (though read on!).
